MACD osc紅柱綠柱問題

input: FastLength(12), SlowLength(26), MACDLength(9);

variable: difValue(0), macdValue(0), oscValue(0);

MACD(weightedclose(), FastLength, SlowLength, MACDLength, difValue, macdValue, oscValue);

SetInputName(1, "DIF短期期數");

SetInputName(2, "DIF長期期數");

SetInputName(3, "MACD期數");

oscValue >0  代表紅柱...可是我怎麼選出來的警示都不是紅柱 @@

程式碼如下

--------------------------------

input: FastLength(12), SlowLength(26), MACDLength(9), Length(9), RSVt(3), Kt(3), HighBound(75);

variable: difValue(0), macdValue(0), oscValue(0), rsv(0), k(0), _d(0);

SetInputName(1, "DIF短期期數");

SetInputName(2, "DIF長期期數");

SetInputName(3, "MACD期數");

MACD(weightedclose(), FastLength, SlowLength, MACDLength, difValue, macdValue, oscValue);

Stochastic(Length, RSVt, Kt, rsv, k, _d);

if close > open

and oscValue > 0 (這行有無結果都一樣)

then ret = 1;
